IPC: H01S5/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To allow adjustment of oscillation wavelength by providing a semiconductor amplifier and a fiber grating which is an external resonator, and also providing a means for changing the optical length of the resonator. SOLUTION: A semiconductor amplifier 2, an optical fiber 1 wherein a grating 10 is formed at a core and lenses 31 and 32 for light to be incident efficiently, are provided. On the optical path of the lenses 31 and 32, a phase adjustment element 5 using electro-optical crystal LiNbO3 is provided.

Title: Sliding correlator
Inventor: TOMINAGA HIDEO
IPC: H04B1/7095
Filed: 1991-12-26
Abstract: PURPOSE:To implement synchronization acquisition at a high speed by shifting a spread code when a match tip number or an unmatch tip number that is smaller exceeds a threshold level even on the way of one period. CONSTITUTION:A control section 18 outputs a sliding signal (f) to a pseudo noise series generating section 22 with the output of a comparator section 7. A threshold level of a storage section 8 is updated to a small count of a comparison selection section 23 with a update signal (e) from the control section 18. When the threshold level is updated into a low level, the pseudo noise series is shifted and counters 16, 17 are reset frequently. A sliding signal detection section 21 counts the signal (f) and outputs a sliding end signal (g) for each prescribed number of times. Upon the receipt of the signal (g), the control section 18 implements synchronization acquisition with a maximum value detection timing signal outputted when the threshold level is finally updated. Thus, the synchronization acquisition is implemented at a high speed.

IPC: G07B3/02
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To exactly detect the remaining quantity of rolled paper without applying any conveyance load to the rolled paper by optically detecting the rotating angle of rotary shaft at time, when the rolled paper is fed out for prescribed quantity, with no contact and detecting the remaining quantity of rolled paper from the displacing amount of this detected angle. SOLUTION: When rolled paper 2 is fed out by ticket issuing operation, a rotary shaft 31 is rotated and a disk 32 is rotated by this rotation.
